Equipment and method for sectional fine sorting of tobacco sheets

Abstract

The invention discloses equipment and a method for sectional fine sorting of tobacco sheets. The equipment comprises a hemp removal device, a tobacco stem detection and removal device, a free-falling type green tobacco and mildewing tobacco detection and removal device and a manual leaf sorting device, which are sequentially arranged. The method comprises the following steps that the raw material of tobacco sheets is fed through an inlet of the hemp removal device, the qualified tobacco sheets are outputted through the free-falling type green tobacco and mildewing tobacco detection and removal device, the tobacco stems in the stem-containing tobacco leaves with the impurity, which are separated by the tobacco stem detection and removal device, are removed by the manual leaf sorting device in a manual stem removal method, the tobacco leaves are mixed into the qualified tobacco sheets for recycling, the impurities in green tobacco and mildewing tobacco-containing tobacco leaves which are separated by the free-falling type green tobacco and mildewing tobacco detection and removal device are removed in the manual sorting method, and then the usable tobacco leaves are mixed into the qualified tobacco sheets for recycling. The equipment and the method for the sectional fine sorting of the tobacco sheets have the advantages that easy implementation is realized, detection efficiency and removal efficiency are high, and automation degree is high.

Description

technical field [0001] The invention relates to a segmented and selected tobacco sheet tobacco equipment and method. Background technique [0002] In the tobacco processing link, tobacco sheets and tobacco stems need to be processed separately, and the "leaf stem content rate" in tobacco sheets is an important technical index to measure the quality of tobacco sheets. In order to obtain higher purity of tobacco sheets, The tobacco stems in the tobacco slices need to be removed as impurities, and reducing the stem content in the leaves can effectively improve the purity of the tobacco slices, thereby improving the quality of the tobacco slices. In addition, in addition to a small amount of tobacco stems, the raw tobacco sheets also contain fibrous impurities, immature green tobacco, mildewed tobacco sheets, and other impurities. The existence of these impurities directly affects the purity of the tobacco sheets. The degree will have a greater impact on the quality of the smok...

Problems solved by technology

The post-winding processing process is mainly used for the separation and processing of leaf stems. It is suitable for occasions where the shape of the tobacco leaves is large and the stems contained in the leaves are relatively thick. Because its floating rate is closer to that of pure tobacco leaves, this process method cannot realize the screening and rejection of small pieces of tobacco with small stems and diameters.

The artificial screening and impurity removal process is generally used in the pretreatment section of the silk production line. Although this
